The Phoenix Contact IB IL 24 DI 4-PAC is a compact Inline digital input terminal for expanding PLC and machine I/O. With four 24 V DC channels and 3-wire sensor connection, it integrates seamlessly into Inline stations and control cabinets, saving space with a 12.2 mm width and ensuring reliable signal acquisition in IP20 environments at a local bus speed of 500 kBit/s.

Designed for demanding industrial automation, the module provides four IEC 61131-2 type 1 digital inputs with defined switching thresholds (0: -3 to 5 V, 1: 15 to 30 V) and short-circuit and overload protection. The supply range of 19.2 to 30 V DC supports stable operation, while process data mapping of 4 bits and minimal configuration simplify commissioning. Robust DIN-rail mounting, operating temperature of -25 to 55 °C, and compliance with overvoltage category II and pollution degree 2 enhance reliability; Inline connectors and coding field are included.

Ideal for machine building, panel building, and distributed I/O expansion, this Phoenix Contact Inline digital input module delivers dependable 24 V DC signal interfacing with fast local bus communication, and it helps reduce wiring time through spring-cage connections, all backed by a 1-year warranty to support continuous operation.
